I don't believe this has been covered, or maybe I'm just slowly going mad .......
Running a Deus with a set of Chef Phones - recently in one of my fields, I had to keep stopping what I was doing as I SWEAR I could hear faint voices ....... turn around, nobody anywhere in sight. Though maybe it was my phone GPS talking from my pocket, so ignored it.
Today I went out WITHOUT my phone, and the little voices are still there every now and then - I'm a totally lucid chap with my own business - I'm sure I'm not going mad, am I ???

Seriously though folk - although 18Khz is incredibly low, is there ANY possibility I am picking up other radio transmissions with the headphones ? Seems to be just that field on the very HIGH ground it happens in.
Anyways, I'm off, got an alligator in the oven for lunch and the car needs painting.
Good NIght
